Architectural Plans and Plan
Sheets
Contract-related documents include the final building contract,
detailed specification sheet(s), and working drawings for con-
struction. This set of paperwork becomes part of the legal founda-
tion for the project. Each document is vital to the building process.
The various plan sheets listed below make up the working draw-
ings that builders and subcontractors typically use to develop their
estimates. Carpenters will use the same drawings to interpret the
design and build the structure.
Many people refer to a set of working drawings as plans or
blueprints. In fact, working drawings are part of the complete
set of architectural plans. Architectural plans include working
drawings, schedules, and other sheets shown in the list below.
Many architectural plan sheets are horizontal (section) views of
the building. The most common plan sheets include floor plans,
foundation plans, and roof plans. The order of plan sheets gen-
erally follows the order of the building process. Elevation views
are usually before building plans to give builders, homeowners,
and trade workers a sense of how the entire project will look on
completion. Not all architectural plan sets will include each sheet
listed below.

9. Window and Door Schedules
10. Details and Section Views
11. Interior Elevations
12. Trade Plans (Mechanical, Electrical, Plumbing)
13. Specifications
The sophistication and detail in a set of construction plans
may vary based on building design, owner’s need, and the ar-
chitect. In any case, enough detail is required to help minimize
mistakes and facilitate coordination within the various trades,
subcontractors, and materials suppliers. In drawing construction
plans, architects, drafters, or builders will illustrate many details
in only one place to eliminate confusion and redundant informa-
tion. For instance, specifying the same stud spacing on every wall
section is not required for most plans.
Title Sheets
The title sheet (Figure 8.2) is the cover for a set of architec-
tural plans. On new construction, the title sheet typically has
a front elevation view of the home. The title sheet normally
includes all pertinent information about the primary parties
involved with the project. The title sheet will list the architect
(designer), owner, builder, and major subcontractors, and it
may include a green home certification program’s seal and the
green verifier’s information. Other sheets in the plan set will
use a title block. The title block organizes some of the same
information from the title page for quick reference on each
page. Page numbers will be part of a title block to help keep
drawings organized.
Plan Visualization
Visualizing the finished home or addition by reviewing a set of
working drawings is a learned skill developed by builders, car-
penters, and other craftspeople. It takes practice to develop the
spatial skills necessary to visualize a three-dimensional building
represented on a two-dimensional sheet of paper. Experienced
carpenters can take a virtual tour in their minds of the finished
building as they read and interpret information in a set of ar-
chitectural plans. As this chapter covers each plan sheet, draw a
mental picture to visualize the information and begin developing
spatial skills. Figure 8.1 illustrates how the 2-D drawing becomes
a real 3-D structure.
Orthographic Projection
Drafters, engineers, architects, and builders use a system known as
orthographic projection to create drawings of three-dimensional
buildings on two-dimensional paper. Ortho means “straight
line” and this projection provides a graphical representation on a
two-dimensional plane. The projection represents objects drawn
with a common relationship; that is, they are in scale with each
other. Common perspectives and drawing techniques are shown
in Figure 8.3.
Acommondrawingperspectiveprovidingathree-dimensional
view (3D) is the isometric view. Isometric views place all horizontal
lines at 30° angles relative to the horizon with vertical lines perpen-
dicular to the horizon. With this method, all lines are to scale and
remain in proportion. An example is shown in Figure 8.3.
n Define and explain the various sheets that make up a set
of architectural plans.
n Identify the sheets in a set of working drawings and ex-
plain the information available from each working drawing.
n Define the most common scales used on architectural
plans. Explain why scales are important and what informa-
tion they make possible on a single plan sheet.
n Give examples of electronic plan scaling aids and software
available to estimators and builders. Explain how these
tools help estimators work faster and more accurately.
n Explain why section views and details are important plan
sheets. How do carpenters and other trade workers use
these views?
n Explain how Building Information Modeling software helps
build energy-efficient homes.

How to Apply the Architect’s Scale Learning to use the
architect’s scale is important to reading and interpreting working
drawings. Follow the steps shown below and refer to Figure 8.7 to
practice with an architect’s scale and develop accuracy and confi-
dence in reading working drawings. The figure in this example is
part of plan sheet A-5 the detached garage from the La Chapelle
Plan But the technique can be used throughout any scaled set of
plans using an architectural ruler.
1. Find the appropriate fraction mark at the end of the scale that
corresponds to the scale of plan sheet A-5. In this example
shown in Figure 8.7, 1>4″ = 1′ is used.
2. Using the 1/4″ scale, set the architectural ruler on the zero
mark and one corner of the garage front.
3. Read across the scale to the other end of the garage and note 22′.
4. On a 1>4″ = 1′ scale, 5½″ is equal to twenty-two 1>4″ seg-
ments; i.e., 22′ as shown on plan sheet A-5. Take a basic ruler
and you will see the garage’s actual measurement on the plan
sheet is 5½″.
5. The area to the right of the zero mark on the architect’s
scale is for measuring inches. For example, you can meas-
ure 9″ on the scale right of the zero mark by counting nine
hash marks.
Civil Engineer’s Scale
On a building lot or larger land area, surveyors use measuring
equipment that divides parts of a foot into a decimal number car-
ried to thousandths of a foot for accuracy; for example, 255.469′
may be the length of a property line. Because of the larger scales,
decimal formatting, and accuracy, surveyors use this standard to
create the property lines on most plot plans. A civil engineer’s
Dimensioning Aids for Working with
Architectural Plans
Reading a set of construction plans requires practice, experi-
ence, and spatial skills. To quickly read rough dimensions or for
estimating; a wide range of computer controlled, electronic, and
manual dimensioning aids are available. Even though these tools
usually provide enough accuracy for estimating and general draw-
ings, always refer to the architectural plans for exact dimensions
and details. Various scaling tools are available to increase accuracy
and speed when estimating; see Figure 8.4.
Architect’s Scale
There are several versions of the architect’s scale; the most com-
monly used is triangular with 11 different scales, one being a
full-size ruler. Common plan scales are shown in Figure 8.5.
The end of each scale has a fraction that designates the par-
ticular scale. In residential construction, 1>4″ = 1′ is the most
common scale used on working drawings, as shown in Figure 8.6.
However, some plan sheets, depending on paper size, build-
ing size, and objects represented, may use 1>8″ = 1′ or other
scales. Be sure to check each sheet for the appropriate scale be-
fore taking measurements.
P r o f e s s i o n a l T i p
Written plan dimensions always take precedence over scaled
and measured dimensions. Variations in printing and paper
can decrease the accuracy of measuring and scaling dimen-
sions from a physical plan set.

Figure 8.5 Eleven scales are available on a triangular architect’s
ruler. The most common used in residential construction is 1/4″ = 1′.
scale can be used to read these large-scale drawings easily. The
civil engineer’s scale divides into six scales; each scale further mul-
tiplies by a factor of 10 for increasingly larger scale drawings. See
the engineer’s scale chart and example for reading a civil engineer-
ing scale in Figure 8.8.
Electronic Scaling Tools
Electronic tools are available for scaling plans when estimating.
Two popular types, the ScaleMaster II and the Scalex PlanWheel
(shown in Figure 8.4), can perform linear, area, and volume
measurements for easy and accurate estimating. Some electronic
measuring aids are wireless and interface with spreadsheets and
estimating software. Some versions have a small calculator built
in to help with adding and subtracting measurements. All dimen-
sioning aids help with calculations required for estimating. In ad-
dition, electronic aids increase accuracy to a higher level and can
decrease overall estimating time.
Working Drawings
Depending on building complexity, roof design, and other vari-
ables, a set of working drawings for a residential home may be 5
to 10 sheets. For basic designs, a simple floor plan, a few speci-
fications, and possibly a roof plan is all many carpenters need
once the building corners are determined with a site plan. The
point is that working drawings may be very simple or very com-
plex depending on the project and the experience level of the
builder and crew members. Using the International Residential
Code, experienced carpenters can easily adjust to a particular set
of working drawings. The complexity of the drawing is a factor
in determining the plan sheet size; standard sizes are shown in
Figure 8.9.
The working drawings provided to contractors for bidding
serve many purposes in the overall construction process. Below
are some applications of working drawings other than physical
construction.
1. Estimating and Take-offs. The builder and subcontractors
use working drawings to calculate all of their materials, labor,
and other expenses.
2. Permitting. In residential construction, the requirement for
plans in the permitting process varies by jurisdiction. Some
architects create a set of plans specifically for permitting; they
may have a slightly different look than actual working draw-
ings.
3. Permanent Record. A set of working drawings constitutes
a permanent record of construction and design, along
with all details and specifications. Provide a set to the
homeowner for future repairs, additions, or remodeling
projects.
4. Legal Record. The working drawings become part of the le-
gal record for the building. If legal issues arise during or after
construction, courts may use working drawings as a basis for
determining important facts.

Using the common 1" = 1" scale, the master bedroom’s
physical measurement is 45/8". Using the 1/4" plan scale
converts it to the actual size of 18'-5".

Presentation and Elevation Viewing
Style
Presentation View
Plan books, internet sites, architects, or builders may provide a
presentation view (Figure 8.10). This is essentially a tool for selling
the plans or home and provides little related to actual construc-
tion detail. Presentation views, in pencil or color, typically show
fully developed landscaping, distinctive features, and even people
to present the finished home in a favorable light. Unless the owner
specifically requests the added perspective provided by a presenta-
tion drawing, it is not included in most construction plans.
Whole House Elevation Views
Elevation views provide a visual and scaled view of the home’s exte-
rior or interior. Most plan sets include views with each side shown
and detailed. Elevations include references to many specifications for
framing and exterior finishes. Roof slopes, ceiling heights, finished
floor heights, and roofing and siding materials are usually identified
on elevation sheets, as shown in Figure 8.11 and detailed as follows:
Roof slope: Roof slopes may not be the same for all covered
sections of the home. For example, dormers, shed roofs, and
garages may have different slopes.
Ceiling heights: Ceiling heights are provided on most elevation
sheets and may be included on specifications or detail sheets.
Exterior finishes: Exterior finishes are usually illustrated and noted
on elevations. In some cases, the street side of a home will be brick
and the other three sides are covered with siding or other materi-
als to meet restrictions of the neighborhood or community.
Topography: The actual lot grade (topography) helps estimators
calculate foundation materials and grading work. Elevations
also illustrate the home’s finished look in relation to grade.
Interior Elevations
Interior finish work such as cabinets, trim work, and built-in
bookcases may have a plan sheet (see Figure 8.12) with interior
elevations so carpenters know where to set these items. Interior
elevations dimension universal design features like lowered
counters or fixtures so carpenters can install the features ac-
cording to requirements. Universal design heights and details
for doors, cabinets, and other features are discussed in other ar-
eas of the text.
Layout and Framing Plan Views
For plan views, a cutting plane is a horizontal line “cutting” the
object for a better view. For example, with typical floor plans, the
horizontal cutting plane is typically at a height that cuts through
doors and windows on exterior walls so they are in the final view.
Removing the area above the cutting plane creates a bird’s-eye view
looking down into the structure like the example in Figure 8.13.
Plot or Site Plan
A site plan (Figure 8.14) contains information verified by a sur-
veyor, engineer, and others. It illustrates important features such
as utility easements, topography, property lines, setbacks, and el-
evations. Site plans usually include the building footprint, drive-
ways, auxiliary buildings, and other constructed features on site
as references. A plot plan, very similar to a site plan, is specifically
for recording a piece of land and shows much of the information
on the site plan without a house on the lot. Some of the important
aspects include the following:
Easements: Any property easements must be specifically located
and identified. It is advisable to check with code officials and
utility companies for restrictions and setbacks related to prop-
erty easements.
Setbacks: All property setbacks shown on site plans should be
verified with local zoning officials before construction begins.
A quick phone call can help eliminate serious code problems
related to building within a setback area.
Benchmark: The benchmark sets the elevation of many con-
struction features, including finished floor levels and founda-
tion heights.
Site plans contain very important information about el-
evation. Each site plan has an elevation called the benchmark.
The benchmark represents a starting elevation that may be
an actual elevation above sea level or, for ease of use, an arbi-
trary number like 100.00′. In either case, all points of eleva-
tion throughout the site plan reference against the benchmark
elevation. Carpenters and masons will use these elevations
as starting points to calculate foundations and finished floor
heights. Masonry workers will use these elevations to build and
check all foundation walls, piers, and other structural compo-
nents of the foundation system.
Site or plot plans have become more significant in today’s
environment of green building. The orientation of the building
is important to operating efficiency. Windows and doors can be
oriented and sized to maximize any solar advantages based on
the home’s location. The site plan can be used to manipulate the
scaled building footprint into the best orientation for solar ef-
ficiency based on location, building size, and limitations of the
building lot. These plan sheets also show protected areas like tree
drip zones and natural areas, as well as areas designated for mate-
rials storage and heavy equipment.
The oldest known plan or drawing dates back to around 2100 BC
and is credited to the Chaldean Prince of Lagash, a city-state
in ancient Mesopotamia. In his time, the prince was known as
an engineer and a builder.

Foundation Plan
The information on a foundation plan provides critical dimen-
sions for structural support features. The height of the cutting
plane should be set to “cut through” any windows, doors, or other
openings in basement walls so the builder can define locations,

The footing projection is the width of the footing beyond the
foundation wall, pier, or column. IRC R403.1.1 Minimum Size
states, “Footing projections, P, shall be not less than 2 inches
and shall not exceed the thickness of the footing.” (2015 IRC,
p. 80) For the example in Figure 8.15, what is the total foot-
ing width based on the footing projection and basement wall
specifications?
Answer: Foundation wall is 108″ concrete with an exterior
footing projection of 34″ and an interior footing projection of
34″ = 16″ total footing width.
type, and other specifics. Take a look at the information below
and noted in Figure 8.15 of important specifications provided by
foundation plans.
Foundation wall type and width: The foundation width as
determined by code or design may not be the same for all
areas of the building.
Window openings: Window type, size, and location may not be
the same at all locations.
Dimension lines: Carefully note dimension lines and their refer-
ence points. They may represent the outside edge, the center-
line, or the inside edge of the object referenced.
Footings and piers: Dashed lines represent the footing width
for foundation walls, piers, and columns. The footing width
beyond the foundation wall, column, or pier on either side is
the footing projection (see Figure 8.15).
Concrete: Some concrete specifications may be listed on foun-
dation plans, but refer to specifications sheets for all pertinent
details.
Local frost lines: The depth of footings below grade must be
defined by local code jurisdictions based on local soil and
weather conditions. In the International Residential Code,
Table R301.2(1), footnote b states, “The jurisdiction shall fill
in the frost line depth . . . with the minimum depth of footing
below finished grade.” (2015 IRC, p. 29)
The floor plan provides the information needed to estimate
many materials like studs, drywall, doors, windows, and floor
framing. Many plan sets include framing sheets for floors, walls,
and ceilings as shown in the following sections. Although not re-
quired, framing sheets help estimators work more accurately and
help carpenters reduce material waste.
Room size and layout: As with any dimension, be sure of
the reference point so the actual work will match the floor
plan. In rooms with appliances, bathroom fixtures, or other
equipment, the point of reference for dimensions is critical
to design. For example, the kitchen cabinets are often
preordered based on floor plan dimensions. A mistake in
reference point here during rough framing means the cabi-
nets may not fit in the finished wall space. See Figure 8.17
and the examples of minimum spacing requirements from
the International Residential Code Figure R307.1, Mini-
mum Fixture Clearances. Always confirm that dimensions
meet any local changes to the model code.
Piers and columns: The surface contact area of support for
framing materials over bearing supports (piers and columns) is
regulated by IRC section R502.6.1. It requires floor joists ends
over bearing support to lap a minimum of 3″ and requires the
boards to be nailed with three 10d face nails.
Plumbing fixtures: IRC Section R307, Toilet, Bath and
Shower Spaces, specifies minimum spacing requirements for
these fixtures. Reading the floor plans correctly while laying
out the walls is critical to assure code-compliant spacing in
all areas.
Electrical and HVAC: Floor plans are used by trades work-
ers to position outlets, switches, home integration systems,
HVAC supply and return registers, and many other compo-
nents of the home design.
Exterior features: Floor plans dimensionalize the place-
ment of decks, porches, garages, and other attached, exte-
rior features. Depending on design, exterior features like
decks may have details specified and illustrated on other
plan sheets.
Floor Plan
Floor plans like the example in Figure 8.16 are usually the most
information-packed of all plan sheets. Like the foundation plan,
the floor plan cutting plane should be at a height that includes all
window and door openings. This sheet defines the size and layout
of all rooms and may include electrical, HVAC, and plumbing
information. If the home design is more complex, however, elec-
trical, HVAC, and plumbing may be on separate sheets to simplify
the view and help eliminate mistakes and oversights during esti-
mating and construction.
Ma t h T i p
A floor plan measures from edge to edge on the exterior. One
exterior kitchen wall shows an outside dimension of 12′-8″.
According to the specifications, all exterior walls are framed
with 2 × 6 studs, 1>2″ gypsum board on the interior, and 1>2″
OSB sheathing on the exterior. Wall-to-wall, what is the maxi-
mum width of the cabinet assembly?
Given dimension is 12′-8″. Subtract the 2 × 6 wall thick-
ness from both sides (5½″+5½″ = 11″). Subtract the gypsum
board and OSB from both sides (1>2″+1>2″ = 1″ × 2 sides
= 2″). Final answer: 12′-8″-11″-2″ = 11′-7″ maximum cab-
inet assembly width.
M08_POWE4171_01_SE_C08_074-093.indd 83 12/4/14 4:04 PM

Figure 8.11 Elevation drawings may identify important framing and finish design requirements, such as roof slope.
Framing Plans for Ceilings and Roofs
Ceiling or roof framing plans provide details for all structural
components and the layout spacing and arrangement of the sys-
tem. For example, in Figure 8.18, spacing and framing details for
all ceiling joists are noted on the ceiling framing plan (sheet A-6).
In addition, the size and type of all materials is defined in the
framing plan.
A ceiling or roof framing plan (Figure 8.18) will show details
of framing for green features such as I-joists, raised-heel trusses,
engineered lumber, or recycled steel. These green and sustainable
design options must be detailed for carpenters to follow the de-
sign specifics. Estimators also need this information for bidding.
Some of the green features on framing plans may be included on
the specifications sheets.
Without a framing plan, carpenters will design a ceiling or
roofsystembasedontheIRCcoderequirementstoprovideacode-
minimum system that meets all standards for safety. However,
using the green features noted above will improve on the mini-
mum design requirements of the International Residential Code
and may reduce materials consumption.
Detail and Section Views
The detailandsectionviews provide very specific information about
a particular construction or design feature. These views provide en-
larged drawings to show specific details. To assure compliance with
design and efficiency standards for the home, carpenters need de-
tail sheets to define materials, techniques, and special applications.
Detail and section views are often combined several to a sheet.
When a particular area of a plan sheet has a corresponding al-
phabetical or numerical indicator, refer to the detail sheets. This
indicator directs the carpenter to a particular enlarged view on the
detail sheet. For example, note the window flashing details from
plan sheet D-1 in Figure 8.19.
One of the most common detail views is a wall section. See
Figure 8.20 for the wall detail from plan sheet D-1. Common prac-
tice is to include one typical wall section and any details unique to
the home’s design or special features. A wall section may include
green features and framing requirements above code minimums
as shown in Figure 8.20. Study detail sheets carefully before con-
struction begins to assure compliance with structural, materials,
and energy-efficiency requirements.
M08_POWE4171_01_SE_C08_074-093.indd 84 12/4/14 4:04 PM

Schedules and Specifications
With a set of architectural drawings, the most common sched-
ule or specification sheet is for windows and doors. Throughout
a plan set, windows, doors, and other components have a numerical
or alphabetical designator corresponding to an entry on the
schedule sheet. Information on the schedule sheet will provide
specifications, model numbers, material type, size, rough open-
ings, manufacturer, and may include a notation of the product’s
efficiency. See the window schedule from plan sheet C-1 in
Figure 8.21. Chapter 43, Windows, Skylights, and Tubular
Day-Lighting Devices, covers the efficiency standards noted on
the C-1 plan sheet.
CAD Programs for Design and
Energy Efficiency
CAD (Computer-Aided Design) software has been available for
building design and estimating for years. Options range from
simple to very sophisticated software and hardware packages for
residential and commercial construction. The most advanced
programs provide materials lists and 3D real-world walkthroughs
and at the same time calculate the impact of materials and con-
struction techniques on building operating efficiency. Stand-
alone estimating and accounting programs are available as part
of fully integrated modeling software called Building Information
Modeling (BIM). BIM is sophisticated software that models many
aspects of a building, including air quality, energy consumption,
and operational efficiency.
CAD (Computer-Aided Design) or CADD (Computer-Aided
Design and Drafting) are very similar. Both are available as
freestanding programs or as part of a total BIM package.

these programs can do is shown in Figure 8.22. Most can produce
a complete set of working drawings for any residential design.
Some engineers, architects, and builders in residential construc-
tion use AutoCAD®. However, AutoCAD requires training and
is primarily a commercial design product. Programs tailored for
residential construction are easy to use and provide many levels
of detail. Some 3D design programs can integrate with account-
ing programs for detailed cost reports and estimating functions.
Modern builders and subcontractors take advantage of tech-
nological advances in communications and software that inte-
grate design, accounting, and scheduling software. These modern
tools save time, reduce errors, and help builders become more effi-
cient and profitable. Learning to work with these programs is a pre-
requisite to management positions in the construction industry.
Building Information Modeling (BIM)
An example of BIM software is the REM/Rate™ software used
by Energy Star HERS raters. This software package provides
energy modeling based on criteria input by the rater, such as
blower door and duct blaster testing, insulation quantity and
quality of installation, energy-efficient lighting, appliances,
and heating and cooling equipment. Using BIM software, a
rater can provide a detailed analysis to the builder or home-
owner of the operating costs and operating efficiencies of the
building.
One of the many functions of BIM software is to compare
products for efficiency and cost. For example, windows of dif-
ferent efficiency levels can be compared to calculate the an-
nual energy cost differences. BIM programs make calculations
based on building orientation and latitude to determine solar
heat gain for windows and doors. The software will calculate
these numbers as part of operating efficiency and energy costs
on an annual basis. Green remodelers and builders use the
reports generated by BIM software programs to help custom-
ers see the advantages of green and efficient components and
materials.
